Food processing in California requires large amounts of water, most of which becomes waste. Since the late 1960s, the major canners, with about 10 plants in the Central Valley, have been irrigating crops with this valuable resource. Many processing plants produce 2 to 4 million gallons per day of effluent during the summer irrigation season. This is sufficient water to irrigate 400 to 800 acres of cropland at each site.
